"Give your guests a special treat around the outdoor fire with edible toasted marshmallow shot glasses filled with your favorite liqueur or specialty drink. S'mores for adults only!"
Toast a marshmallow—regular and jumbo size—over your campfire until it is deeply golden brown. Be careful about two things: first, don’t stick your stick the whole way through the marshmallow; and second, do not set your marshmallow on fire. Gently scoot your marshmallow off the roasting stick onto a plate to cool completely. Make a s’more while you wait.
As the marshmallow cools, the center should cave in like a molten sugar crater. Fill the crater of your cooled marshmallow with the booze of your choice—I recommend something bracing, such as Fernet Branca—and shoot it quick before the marshmallow dissolves. Chase your shot by indecorously shoving the marshmallow in your mouth. You’re welcome.
